Alerts are missions in DC Universe Online in which 4 players are joined together in a group and placed in an instance, the only exception being the very first alert players have access to, ALERT: Calling all Heroes!, and its villain counterpart, ALERT: Villains Wanted!, which are solo missions.

The group works together to complete a series of missions within the instance. Each Alert has several smaller bosses leading up to a main boss at the end.
